● features: the grouting pipe is divided into secondary grouting pipe (ccll-y grouting pipe, qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)The secondary grouting pipe can only be grouted once and cannot be reused.

Push the rock powder and sundries that are not washed, remain at the hole bottom, or stick to the hole wall out of the grouting range, install and lower the grouting pipe grout stop plug, mixer and other facilities in the hole.CologneGrouting pipeproduction,CologneSeamless pipe,CologneGrouting pipe,2023-11-0912:55:15● features: the grouting pipe is divided into secondary grouting pipe (ccll-y grouting pipe qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.

● features: the grouting pipe is divided into secondary grouting pipe (ccll-y grouting pipe,CologneSteel pipe, qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)Compared with sleeve valve pipe grouting method, the common disadvantages of grouting pipe grouting method, flower pipe grouting method and drill pipe grouting method are that it is easy to emit slurry along the pipe wall and the grouting layering effect is poor. These disadvantages are particularly prominent when using slurry with good fluidity and long initial setting time; The utility model has the advantages of simple equipment and process, good flexibility, fast construction speed, and is more suitable for situations requiring rapid response.Cologne,Niigata
